9 Claims;

My invention relates particularly to that class of dental furniture that may lee-equipped with those devices and appurtenances that a dental practitioner employs in the practice of his profession and that may occupy a position in close approximation to a dental operating chair so as to be readily accessible to the operator and easily conveyed to the patient in the chair.

The principal objects of my invention are toi provide a cabinet that may be closed and locked and within which all of the operating appliances may be housed when not in use, to provide an equipment mounting standard that serves to so support said operating appliances as to permit 1 their withdrawal from the cabinet into convenient position with respect to the patient in the chair, and also serves as a reinforcing support for the cabinet structure within the walls of which it is enveloped.

Other objects of my invention are to provide a supporting standard that may be easily set up and attached to the floor and having means for the convenient attachment of the operating appliances and the necessary electrical and fluid connections thereto, and which readily lends itself to the subsequent application of the cabinet structure thereto which may conveniently envelop the operating structure thus assembled with freedom of access.

Further objects of my invention are to provide a cabinet with walls having openings suitably located therein through which the various operating appliances and devices may extend when pro-- jected outwardly to a position convenient for use,

and having suitable closures for protecting said appliances and devices within the cabinet Walls when in retracted position and not in use.

My invention comprehends an equipment cabinet particularly adapted for use in battery assemblage such as may be conveniently employed in institutions of learning or in onices wherein several operators may have chairs disposed between adjacent cabinets and utilize the equipment devices conveniently disposed in the opposing sides of the relatively adjacent cabinets.

My invention also includes all of the various novel features of construction and arrangement as hereinafter more definitely specified.

In the accompanying drawings, Figure 1 is a plan View of an equipment cabinet constructed in accordance with my invention; Fig. 2 is an elevational view of the cabinet as viewed from the front of the cabinet depicted in Fig. 1; Fig. 3 is a plan sectional view of said cabinet shown in a position reversed from that shown in Fig. 1 and having the upper part of the basin end of the cabinet broken away and shown in section to reveal the various enclosed appliances and their supporting standard; Fig. 4 is an elevational view of the cabinet as viewed from side of the cabinet 5 opposite that shown in Fig. 2 and the side toward the observer in Fig. 3; Fig. 5 is an end View of the cabinet as viewed from the left end of Figs.

1 and 2 and from the right end of Figs. 3 and 4; Fig. 6 is a sectional view taken through the cabinet on the line 6-6 in Fig. 2, certain parts in the plane of section being omitted for convenience of illustration; Fig. 7 is a sectional elevation of the bracket-like supporting standard with the various appliances attached thereto and assembled in 5 operative relation prior to positioning and attaching thereto the housing, comprising the cabinet structure including its walls; Fig. 8 is a plan sectional view of the engine motor mounting and supporting standard with a fragmentary section of the cabinet structure including the corner stiles and end wall attached; Fig. 9 is a side elevational view of the engine motor mounting; Fig. 10 is a transverse sectional view of said engine motor mounting taken on the line l0-lil in Fig. 9; Fig. 11 illustrates diagrammatically two of the cabinets assembled in battery formation in relation to an interposed operating chair; Fig. 12 is a perspective view of open ended cabinet'structure arranged to be shifted into engagement with the supporting standard, upon which the supported appliances havebeen mounted, and to which said open ended cabinet structure may be conveniently attached and the cabinet end applied to complete the equipment cabinet, ready for use; Fig. 13 is a perspectiveview of the right hand half of the end wall section adjacent to the basin as shown in Fig. 5; Fig. 14. is a perspective view of the right hand half of the end wall section adja- 1 cent to the basin as shown in Fig. 5 and being 40 complementary to the end wall section shown in Fig. 13 to form the medial section of the end wall of the main body of the cabinet structure; and Fig. 15 is a perspective view of a modified form of the supporting unit illustrated in Fig. '7.

In said figures, the equipment cabinet comprises the front Wall E, rear wall 2, end walls 3 and l, shelf 5, the switch-board panel 6 and the inclined panel 7, top cover 8 and base-board9.

The front wall I is provided with the opening it, affording access to the chamber I2 and provided with the slidable closure l3 having the hand-holds l5 and it, the drawers l7, l8, l9, and the slide or drawouttable 20, which serves also as a closure for thechamber 2i. Said wall I also includes the control panel 22, having the control knobs 25, 26, 2'l, 28, 29 and 30 for the control of the low voltage switch, air pressure valve, warm air syringe valve, low voltage control, cautery and pulp tester control and mouth lamp control respectively, all being of well known construction and not specifically illustrated.

The switch-board panel 5, which connects the shelf 5 with the inclined panel 1, has mounted thereon the gas burner 32 and is provided with the air cock gas cock 35, line voltage outlet 36, master switch 3l, red pilot light 39, white signal light 110, and the signal switch ii, the functions of which are well known in the art and consequently are not herein described in detail.

The inclined panel i, which extends between the switch-board panel 6 and the top cover 8 is provided with the X-ray film. viewing compartment window 42 having the frame 63, and carries the illumination control switch knob 45 for turning on and off the lamp, not shown, but which is adapted to illuminate said X-ray film viewing compartment, and to light up the window 42.

Within the chamber I2 a suitably provided bracket 46 is provided upon which is supported the spray bottle 47, the air cut-offAfi removably supported in the holder 50, and the warm air syringe 52 removably supported in the holder 53. Said air cut-off ts being connected with a source of air by the flexible tubing 55 and the warm air syringe 52 being connected with the source of air supply by the flexible tubing 55, it is obvious that both said cut-ofi 49 and syringe 52 can be moved to any desired position within the range of the length of said flexible tubing.

The rear wall 2 of the cabinet is provided with the opening 5?, affording access to the chamber 59, and provided with the slidable closure 60, having the handholcls SI and 52 by which it may be moved toward the right. as shown in Fig. 4, to close the chamber 59 or moved toward the left to the position shown in said figure to open said chamber.

The front wall I and rear wall 2 are conveniently joined together in integral relation by the end wall 5, shelf 5, switch-board panel 6, the inclined panel i and the top cover 8 to form an open ended cabinet structure, as shown in Fig. 12, which is arranged to be subsequently closed by the end wall 3 comprising the several separately assembled sections 63, M, 65, 55 and 61 as hereinafter more definitely described.

The equipment mounting standard H3, as best shown in Fig. '7, is in the form of a supporting and reinforcing bracket and comprises the horizontal base II, and the vertical upright in the form of a standard plate 12 having its outer plane surface is coincident with the end wall 3, said base and standard being rigidly connected by the transversely extending stiifening rib I5.

As shown inv Fig. 7, the base 'II rests upon the fioor covering 16 such as linoleum, and is provided with an opening TI which is arranged to substantially register with a'similar opening 18 in the floor 79 which, as shown, is composed of concrete, but may be of any other suitable material employed in building construction. Said base is attached by the screws Bil to the floor plate 8i, which in turn is attached by the bolts 82 to the tie-bars 83 disposed beneath the floor I9, and which is rigidly held engaged with relation to said floor.

As best shown in Fig. 7, the equipment mountingstandard may be first erected and secured to the floor I9 and the various equipment appliances and devices may be mounted thereon and. the connections made independent of the enclosing or enveloping cabinet structure, thereby ,greatly facilitating the assemblage of the integral parts to form the equipment unit about which the cabinet structure may be subsequently assembled.

Referring again to Fig. 7, the wash-basin 85 is attached to and supported by the vertical standard plate 12, and has its hot and cold water supply pipes 88 and 8? respectively extending through said standard '12 and downwardly through the openings TI and 18 in the base II and floor 19 respectively, to their sources of supply.

Similarly, the waste water pipe 89 is extended through said standard '52 and said openings I1 and E8 to a proper waste outlet such as a sewer. As shown in Figs. 3, 4 and 5, the water from. the pipes 86 and Si is directed into the basin 85 through the goose-neck faucet 90 and the hot and cold water supply is controlled at said basin 85 by the valve levers or handles 9i and 92. The water supply may also be controlled by the valves 93 and 94 respectively included in said hot and cold water supply pipes 86 and 81 within the cabinet closure.

The spittoon 95, shown in Figs. 3 and 4, is mounted on the swingable arm 96, which, as best shown in Fig. '7, is pivoted to swing horizontally on the bracket 91. Water is supplied to the spittoon through the goose-neck faucet 98 which is connected by suitable piping extending through the arm 96 with the conveyer pipe 99 in a well known manner, said water being controlled by the automatic shut-off valve I80 which connects the conveyor pipe 99 with the cold water supply pipe 83' through the branch pipe connection IUI.

By mechanism I02, of well known construction, the swinging outwardly of the spittoon on the bracket 9'! to its operative position with respect to the operating chair 35, see Fig. 13, water is permitted, by reason of the automatic actuation of the valve I053, to pass through the valve Hill, the pipe 99 and the goose-neck faucet 98 into the spittoon 95; however, movement of said spittoon back into its inoperative position in the cabinet automatically actuates said valve Illit to shut off the water supply to said faucet 98, so that no water can flow into the spittoon when it is not in proper position for use.

The electric engine I95 illustrated is the cord driven type and is mounted to swing into various operative positionsin proximity to the chair I65. Said electric engine I06 is pivoted at Hill to the free end of the bracket H19 which projects from the electric motor III], thus permitting said engine to swing horizontally as a whole, the several arms of which are capable of permitting the driven tool, such as the hand-piece II3 to assume a universal range of movement, as is well known in the art. I

The motor III] is mounted for lineal adjustment into and out of the cabinet whereby it may be extended, as shown in Figs. 8 and 9, free of the cabinet as indicated in Fig. 11. It will be observed by reference to Figs. 8 and 9 that the motor H9 is supported on an extensible arm II l which is slidably mounted in the slide-block H5 and limited in its lineal movement by the stop pin I I6 projecting from said arm I I4 into the slot I I! in the cover'plate I I9 which retains said arm H4 in the guiding groove I20 in which it is arranged to slide, the cover plate II9 being secured to the slide-block IN: by the screws I2I.

The range of lineal movement of the motor I I0 and the engine pivotally supported thereby is greatly increased by reason of thhe fact that the slide-block H5 is mounted for further linear movement on the slide-bar I22 which is mounted on suitably provided bosses I23 and I25 projecting inwardly from the inner surface of the vertically disposed standard plate 12, and said slide-bar I22 is secured to said plate by the screws I26 and I21, as shown in Fig. 8.

The slide-bar I22 slidably extends through the groove I29 in the slide-block H5 and is slidably retained therein by the cover plate I35 which is secured to said slide-block II5 by the screws I32.

By the arrangement thus described it will be seen, upon inspection of Fig. 8, that the slideblock II5 has a range of movement substantially limited only by the bosses I23 and I25 adjacent the corner stiles I35 and I35 of the cabinet structure to which the end wall 3 is attached, thus permitting the motor IIll with its engine I06, to be projected well beyond the Wall 2 of the cabinet, as illustrated in Fig. 11. The motor H0 is conveniently connected in a well known manner to be controlled by the foot operated controller III having the operating lever I I2.

The bracket table I39 is pivotally mounted on the jointed outer extension I 40 of the bracket table arm M2 which is pivoted to'swing about a vertical axis on bracket I53. Said bracket is secured to the standard plate 12 and projects inwardly therefrom above the bracket 91 that swingably supports the arm 56 of the spittoon 95.

As best illustrated in Fig. 7, the opening 11 in the base II conveniently aifords entrance into the cabinet of the gas pipe I 35 having the control ling valve I (I6, and the air pipe I 49 having the controlling valve I55, and also aifords entrance of the electrical conduit I5I leading to the high voltage receptacle I52 and the electrical conduit I53 leading to the low voltage receptacle I55.

As shown in Figs. 1, 2, 4 and 5, the lamp I55 and the soap dispenser I51 are supported by the standard plate 12 and project outwardly from the end wall 3 of the cabinet in suitably disposed relation above the wash basin 85 to aiford illumination and cleansing material when required.

As shown in Fig. 5, the end wall 3 is composed of the assembled wall sections 63, 6d, 65, 66 and B1, and, as best illustrated in Figs. 13 and 14, the wall sections 64 and 65 are formed to embrace the wash-basin 85 and the waste water pipe 89, the section 64 having the rectangular recess I59 arranged to receive the wash-basin 85 and the semi-circular recess I55 arranged to receive the waste water pipe 89, and the section 55 having the rectangular recess I62 arranged to receive the wash-basin 85 and the semi-circular recess I63 arranged to receive the waste water pipe 89.

The wall section 64 is also provided with the aperture I55 through which the nipple section I56 of the hot water supply pipe 86 extends, and the wall section 65 is also provided with the aperture I61 through which the nipple section I59 of the cold water supply pipe 81 extends.

Said end wall sections 63, 64, I55, 66 and 61 may be conveniently attached to the standard plate 12 or to the corner stiles I 35 and I36 of the cabinet structure or to both as may be deemed advisable, to form the end wall 3.

In the form of my invention illustrated in Fig. 15, the standard plate I?! of the standard I10 rises from the base I12 being connected therewith by the rib I13, and having the perimetral flange I15 conforming to the internal outline of the open end margin of the cabinet structure shown in Fig. 12.

My invention is particularly advantageous in that the standard III may be set up and its base 1| attached to the floor, and the various operative appliances, apparatus and devices employed by the operator mounted thereon without inconvenience, as illustrated in Fig. '7, after which the assembled open ended cabinet structure such as illustrated in Fig. 12 may be pushed into position to envelop said appliances, apparatus and devices as are to be enclosed. The cabinet thus positioned may then be securely attached to said standard 15 by means of the corner stiles I35 and I35 and the end sections 63, 64, 65, 66, and 51 which are assembled to complete the end wall 3, as shown in Figs. 3 and 5.

It will be obvious from an inspection of Figs. 12 and 15 that after the various operative appliances, apparatus and devices, as shown in Fig. '1, have been mounted upon the standard I10, shown in Fig. 15, the open ended cabinet structure shown in Fig. 12 may be pushed into such position that the free margins of the walls I and 2, the shelf 5, inclined panel 1, and top cover 8 so overlap the perimetral flange I15 as to permit said margins to be directly attached to said flange I15. In this form of my invention, the standard plate I'II may if desired serve as the end wall of the cabinet without the further application of complementary end wall sections, such as illustrated in Fig. 5.

The cabinet structure thus constructed and assembled not only aifords convenience in assembling, repairing and replacing of the various apparatus, appliances and devices employed by the operator, but it provides a cabinet structure that is so braced and supported by the supporting standard to which it is removably attached as to afiord a rigid envelop, for the parts to be enclosed, that may be formed of relatively light material.

The dental equipment assemblage herein depicted is particularly applicable in use in colleges or large dental offices where a number of operators are employed, and wherein a number of the equipment assemblages may be arranged in battery formation, as shown in Fig. 11, an operator being posed in the position between two adjacent assemblages, and in convenient position to easily withdraw from the opposed sides of said assemblages the apparatus, appliances and devices which he desires to employ.

I do not desire to limit my invention to the precise details of construction and arrangement as herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention as defined in the appended claims.
